I recently Installed jabberd 2.1.21 on a centos 5.1 box.
Both storage and authentication are via postgresql.
I also have samba and winbind configured.
I have compiled and installed jabberd, can launch it, but am
having issues registering users. When attempting to register a user, the
client throws an error (error varies with client).
There are records added to the database, one in the authreg
table, and one in the active table.
Debug output contains the following:
C2S : sx (chain.c:93) calling io read chain
C2S : sx (io.c:234) decoded read data (318 bytes):
<response

The same thing has happened with several clients.
Any insight into this would be greatly appreciated

Which ones?
Have you checked h

gsasl's DIGEST-MD5 implementation doesn't really do the 'be
liberal
in what you accept' thing, and as such is incompatible with
a large
number of currently deployed Jabber clients. If you can't
dictate to
your users which clients they use, you're out of luck.
Jabberd2 does have a Cyrus SASL implementation too, but I
haven't
been as proactive in maintaining this as I would like, and
it may not
work in current releases. I'm not sure when I'll have time
to check
this out properly, and I'm also not sure for how much longer
I'll be
(professionally) interested in maintaining it - I suspect
we'll
strongly consider transitioning to a Jabber server with a
supported,
stable, SASL implementation at our next major upgrade. gsasl
is
pretty much useless from an enterprise perspective.
Cheers,
Simon.

Your Insight is greatly appreciated. I was able to solve
the problem by disabling the DIGEST-MD5 mechanism. This
particular deployment in on a secured internal network, so
using the PLAIN mechanism does not pose a severe threat.
Plus, I had planned on deploying TLS anyway, almost makes it
a moot point.
Thanks again
